Abstract The reaction between 1,5‐diethenylnaphthalene and sec ‐butyllithium produces a new difunctional organolithium initiator which is soluble in non‐polar solvents and effective in the synthesis of styrene‐isoprene‐styrene triblock copolymer. Monomodal molecular weight distributions are observed for block copolymers and styrene homopolymers. The microstructure of polyisoprene blocks is similar to those polymers initiated by butyllithium in the same solvent.
